error when building with cmake: 'cuda_compile_and_embed' not found

[HugoPhibbs]

Hi, I'm trying to build this on the rt-dbscan branch.

I'm using Cmake 3.12.0. Basically the output is:

../cmake-3.12.0-Linux-x86_64/bin/cmake ..
CMake Error at CMakeLists.txt:19 (cmake_policy):
  Policy "CMP0146" is not known to this version of CMake.
